I mean , currently running device is iPhone 4 or iPhone 5.

I need to check the device , is that iPhone

Answer 1

#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
#define IS_IPHONE_4 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 480.0f)
#define IS_IPHONE_5 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 568.0f)
#define IS_IPHONE_6 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0f)
#define IS_IPHONE_6PLUS (IS_IPHONE && [[UIScreen mainScreen] nativeScale] == 3.0f)
#define IS_IPHONE_6_PLUS (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 736.0f)
#define IS_RETINA ([[UIScreen mainScreen] scale] == 2.0f)

Based on the answers of this question you could determined which model your are using by this:

NSString *deviceModel = [UIDevice currentDevice].model;

Results can be one of the values: iPod touch, iPhone, iPad, iPhone Simulator, iPad Simulator

For specific model which version you are using could be determined by creating a Category on UIDevice.h class like this:

UIDevice+Utilities.h

#import <UIKit/UIKit.h>

@interface UIDevice (Utilities)

- (CGFloat)deviceModelVersion;

@end

UIDevice+Utilities.m

#import "UIDevice+Utilities.h"
#include <sys/types.h>
#include <sys/sysctl.h>

@implementation UIDevice (Utilities)

- (CGFloat)deviceModelVersion
{
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *machine = malloc(size);
    sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString *platform = [NSString stringWithUTF8String:machine];
    free(machine);

    if ([platform rangeOfString:@"iPhone"].location != NSNotFound)
    {
        return [[[platform stringByReplacingOccurrencesOfString:@"iPhone" withString:@""] stringByReplacingOccurrencesOfString:@"," withString:@"."] floatValue];
    }
    else if ([platform rangeOfString:@"iPad"].location != NSNotFound)
    {
        return [[[platform stringByReplacingOccurrencesOfString:@"iPad" withString:@""] stringByReplacingOccurrencesOfString:@"," withString:@"."] floatValue];
    }
    else if ([platform rangeOfString:@"iPod"].location != NSNotFound)
    {
        return [[[platform stringByReplacingOccurrencesOfString:@"iPod" withString:@""] stringByReplacingOccurrencesOfString:@"," withString:@"."] floatValue];
    }
    else if ([platform rangeOfString:@"i386"].location != NSNotFound || [platform rangeOfString:@"x86_64"].location != NSNotFound)
    {
        return -1.0; //Currently it is not possible (or maybe it is, but I do not know)
                     //which type of simulator device model version your app is running
                     //so I am returning -1.0 device model version for all simulators types
    }

    return 0.0;
}

@end

Example how to call function deviceModelVersion:

CGFloat deviceModelVersion = [UIDevice currentDevice].deviceModelVersion;

Possible results could be 1.0, 1.1, ..., 2.0, 2.1, ..., 3.0, 3.1, .., 4.0, 4.1, .., 5.0, 5.1, ...

To determine if it is iPhone 5, you would have

deviceModel : "iPhone" 

and

deviceModelVersion : >=5.0 and < 6.0

Answer 3

I actually found a #define that does the trick

#define IS_IPHONE_5 (fabs((double)[[UIScreen mainScreen] bounds].size.height - (double) 568) < DBL_EPSILON)

Answer 4

Add this code:

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
        if ([[UIScreen mainScreen] respondsToSelector: @selector(scale)]) {
            CGSize result = [[UIScreen mainScreen] bounds].size;
            CGFloat scale = [UIScreen mainScreen].scale;
            result = CGSizeMake(result.width * scale, result.height * scale);

            if(result.height == 960) {
                NSLog(@"iPhone 4 Resolution");
                resolution_number = 1;
            }
            if(result.height == 1136) {
                NSLog(@"iPhone 5 Resolution");
            }
        }
        else{
            NSLog(@"Standard Resolution");
        }
    }

Add This Macros to your code:

#define HEIGHT_IPHONE_5 568
#define IS_IPHONE   ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
#define IS_IPHONE_5 ([[UIScreen mainScreen] bounds ].size.height == HEIGHT_IPHONE_5 )

then just check whenever you needs..

if (IS_IPHONE_5) {
    //Code for iPhone5
}else{
    //Code for earlier version
}
